INJECTOR ATTACHMENT FOR AIR OR STEAM PUMPS.

Specification of Letters Patent. Application filed March 15, 1910.

Patented Apr. 16, 1912. Serial No. 549,504.

To all whom it may concern. v

Be it known that I, FRANK S. MORGAN, citizen of the United States, residing at Nevada City, in the county of Nevada and State of California, have invented new and useful Improvements in Injector Attachments for Air or Steam Pumps, of which the following is a specification.

This invention relates to an injector attachment for automatically priming steam pumps or pumps operated by compressed air.

The object of this invention is to provide a simple, reliable priming attachment for pumps. If for any reason a pump loses its water, the injector will pick the water up and fill the pump, thus keeping the pump primed whenever it happens to lose its water. The old way of priming the pumps is by taking water from the column above, and when the water is all gone out of the column, water has to be poured down the column from above. This takes time, and when one is pumping out a mine with a great amount of water coming in, one cannot afford to close down the pump, as one often loses what has already been gained. By my attachment the water is taken from the sump, and should the pump stop, the injector will be pumping water and will take but a few moments to prime the pump. The attachment is placed on the pump so that the water is put into the top and bot tom valves at the same time. The force with which the injector places the water into the pump keeps the valves from ever having any foreign matter lodging under them. By my injector attachment the pump is kept full of water, thus keeping the pump running at an even speed. When a pump loses its water it will speed up, and often times a pump will wreck itself before one can reach it to slow it down.

The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which-' Figure 1 is a plan view, showing a steam pump with the injector attachment. Fig. 2 is a cross-section through the valve chest, showing connections.

In the practical and successful embodiment of my invention I attach to the water end A of a steam or air pump, a suitable steam or air injector 2 having a steam connection 3 with the feed leading to the steam end of the pump, and a suction pipe 4 extending to the bottom of the well or sump from which water is drawn by the pump through its suction 5,

lost pumps are constructed so that the suction pipe 5 and discharge pipe 6 may be connected on either side of the pump, as conditions necessitate; one side being closed with plugs. In carrying out my invention I take the plugs out on one side and connect the discharge pipes 7-8 of the injector 2 respectively with the casings of the inlet and outlet valves 9-10. Part of the discharge from the injector passes through pipe 7 and is led below the inlet valve 9, and part is led above the discharge valve 10. In this way the injector operates to prime both the top and bottom valves at the same time.

In such work as sinking a shaft, the bottom must be kept practically clear of water to enable the miners to work. On work of this kind the steam injector could be kept running continuously, as it makes no dilferpence whether it has water or not.

The operation of the apparatus is as follows: Should the pump, while working, lose its water from the suction pipe 5 for any cause, the operator has only to start the injector 2 by admitting steam, and it will then inject water through the pipes 7-8 into the chests of valves 9-10, thus priming the pump and restoring water in suction pipe 5, when the pump will then again become effective.

Both suctions 4-5 should be made of rub- 4 her with strainer on end of each, in order that suctions may be moved around as conditions demand.

Manifestly the primer is equally effective to use when starting operations, and if desired, may be run continuously, as it does not adversely effect the pump when running,

An important advantage resulting from the use of this apparatus is that the valve seats are at all times kept clean and free from foreign matter, due to the force with which the injector discharges fluid into the pump, thus dislodging any sand or sediment. This attachment will work the same with compressed air as with steam.

In case a pump is not arranged to connect suction and discharge on either side, all I have to do is to drill a hole! in the bottom and top of the ater end of the steam pump ed to the manifold, and a suction pipe conand thread each hole With common pipe nected tot-he injector and adapted to supply thread.
